Blanche fuji's Album: Elevator Manufacturers Share The Point

Passenger elevators are used to carry passengers and require complete safety features and certain interior decoration. The Fuji Elevator Manufacturers below will share what the passenger needs to know: According to the drive classification, it can be divided into AC elevator, DC elevator, hydraulic elevator, rack, and pinion elevator, screw elevator. The AC elevator is driven by an AC induction motor. The AC induction motor is divided into AC single speed, AC double speed, AC voltage speed regulation, AC frequency conversion voltage speed regulation, according to the drag mode. The AC elevator is driven by an AC induction motor. The AC induction motor is divided into AC single speed, AC double speed, AC voltage speed regulation, AC frequency conversion voltage speed regulation, according to the drag mode. The DC elevator is driven by a DC motor. The rated speed of such elevators is generally above 2.00 m / s. The hydraulic lift uses an electric pump to drive the liquid flow and the car is lifted by the plunger. The rack and pinion type elevator is an elevator. The guide rail is processed into a rack. The cage is provided with a gear that meshes with the rack, and the motor drives the gear to rotate to lift the cage. The screw jack is an elevator. The plunger of the helicopter lift is machined into a rectangular thread. A large nut with a thrust bearing is mounted on the top of the cylinder, and the nut is driven by the reducer (or belt) to rotate through the reducer. The motor allows the spiral cage to rise or fall. Once the passenger elevator is in trouble, it can be life-threatening, so passengers must be vigilant. The prompts are as follows. First of all, pay attention to the ultimate load of the elevator. Please voluntarily withdraw when overloading. Secondly, passengers should take care of the elevator facilities and do not press the button and slam the door. The third is to report the sabotaging behavior to the public security department in a timely manner. Last but not least, if you suspect a malfunction or episode, press the alarm button and as many floor buttons as possible.
